The Seiko Men's Automatic Stainless Steel Watch boasts high-tech Japanese automatic movement hidden behind classic analog styling. Precise 21-jewel Japanese automatic movement keeps this watch functioning without a battery--it powers automatically with the movement of your arm. This high-tech feature is tucked away behind the watch's black dial, which boasts luminous silver-toned hands and baton hour markers. The dial also sports a date window at the three o'clock position, and the entire dial is protected by a Hardlex mineral crystal. Keeping all of this securely on your wrist is a brushed-and-polished stainless steel link bracelet that closes with a fold-over clasp. Other features include a stainless steel case with an exhibition case back and water-resistance to 99 feet (30 meters).
